In the equation #2KClO_3 -> 2KCI + 3O_2#, how many moles of oxygen are produced when 5.05 m of #KClO_3# decompose completely?
7.58 moles of
There are multiple lines of reasoning for solving this. Let me give you the most detailed:
You start with a plan: we will convert moles of
You will get 3 moles of
Now let's substitute the number of moles of
Finally, since we started with three significant figures, we have to end up with three significant figures since all we did was multiply and divide, so...
